mindspore.ops.standard_normal

mindspore.ops.standard_normal(shape, seed=None)

Generates random numbers according to the standard Normal (or Gaussian) random number distribution.

$$f(x)=\frac{1}{\sqrt{2\pi }}{e}^{(-\frac{x^2}{2})}$$

Warning

The Ascend backend does not support the reproducibility of random numbers, so the seed parameter has no effect.

Parameters

• shape (Union[tuple, Tensor]) – The shape of returned tensor.

• seed (int, optional) – Random number Seed. Default None .

Returns

Tensor

Raises

• ValueError – If shape is a tuple containing non-positive items.

• ValueError – If shape is a Tensor, and the rank of the Tensor is not equal to 1.

Supported Platforms:

Ascend GPU CPU

Examples

>>> import mindspore
>>> shape = (4, 4)
>>> output = mindspore.ops.standard_normal(shape, seed=5)
>>> print(f'output shape is {output.shape}')
output shape is (4, 4)
(4, 4)
